ANSWER

EXPLANATION
Coterminal angles are angles in standard position that have the same terminal side.
To find an angle in standard position that is coterminal with

We add or subtract multiples of

The first addition gives,

We add the second multiple to get,

Since this is the maximum value among the options, we end the addition here.
Let us now subtract the first multiple to get,

We end the subtraction here because this is the least value among the options.
Therefore the angles that are coterminal with

are
No, it does not and it's not supposed to. A trend line is drawn to go through in the best way possible, to go through the "center" of the points as best as it can. It may hit some of the points, but not all of them. Generally, the idea is to try to get the trend line to have as many points "above" it as it does "below" it to say you've gone through them evenly.

Answer:

Step-by-step explanation:
Since this is a 30-60-90 triangle, we know that the sides have the following characteristic:
The side opposite to 30 degree angle: n
The side opposite to 60 degree angle: 
The side opposite to 90 degree angle: 2n
Since we know that 7 is opposite to 30-degree, and x is opposite to 60 degree, than we know that x = 
The first relation gives two y-values for any given x-value (except x=6).
y² +x = 6 . . . . . is not a function
